Boiler Water Treatment

Untreated or poorly treated boiler water leads to scale on the heat transfer surfaces, corrosion of tubes and condensate lines, and carry-over into the steam. The results are higher fuel bills, unplanned shutdowns and costly tube failures. Target supplies complete boiler water treatment programs for fire-tube and water-tube boilers in factories, hotels and hospitals.

What a Target boiler program covers

• Pre-treatment of feed water: softeners, dealkalisers or reverse osmosis to remove hardness before it reaches the boiler
• Oxygen scavengers to remove dissolved oxygen and prevent pitting corrosion
• Scale inhibitors and dispersants to keep residual hardness and iron in suspension so they leave with the blowdown
• Alkalinity and pH control inside the boiler
• Condensate treatment with neutralising amines to protect return lines from carbonic acid corrosion
• Dosing equipment: dosing pumps, tanks and controls sized for your boiler house

Testing, control and service

Chemicals only work when the dose is right. We set control limits for your boilers, train your operators to run simple daily tests, and visit regularly to check water analysis, blowdown rate and chemical consumption. Each visit ends with a service report so you can see how your system is performing. Water balances, blowdown and dosing are calculated with our ChemTrak software, and readings are tracked over time in Krenos.

Why it pays back

• Clean heat transfer surfaces mean lower fuel consumption
• Correct blowdown saves water, energy and chemicals
• Protected tubes and condensate lines mean fewer shutdowns and longer equipment life
• Recovering more condensate cuts make-up water and treatment cost
